Why doesn't discont=true work in this ca...

Maple 15

I am trying to plot the cdf of a binomial random variable, which has jump discontinuities at each of the integers with positive probability mass. Typically, when plotting a piecewise function, one would prefer not to have Maple connect all the points of discontinuity with a vertical line, and discont=true achieves that. Why doesn't the following command yield the expected results:

with(Statistics):

with(plots):

X:=RandomVariable(Binomial(25,.65)):

Multinomial Distribution in Maple?...

Maple 15

Hi,

How does one implement the multinomial probabiility distribution in Maple? If it's not available in Maple, what would be an easy way to define one?

Thank!

How do I create histogram for a discrete...

Maple 15

Hi,

I am relatively new to Maple and I am seeking an efficient way to create a probability histogram for a discrete probability distribution. For example,

x:      1     3   5    7

p(x): 1/8 1/4 1/2 1/8

I would like rectangles with height corresponding to the probabilities with bases centered at each x value, allowing for the possibility of gaps in the distribtuion.

Hi,

I have what I hope is an easy problem to answer. How would one go about having Maple solve a "vectorized" initial-value problem. For example,

y'(t) =[t^2,exp(t)], y(0)=[-1,1]. Find y(t).

Thanks!
